hi! yes I been looking at the coop build forums. I have jersey giants,Plymouth rocks and easter eggers. we plan to add more in spring, turkeys, guineas and some bantams, maybe a duck or two, oh an peacock. walls are 6' vents at top of peak and are closeable. but how far apart should roost bars be? 12 or 15"?? oh the coop will match our home too once stained and chinked.
